Last night, as the governor of Puerto Rico Luis Fortuño held a political fundraiser in one of the salons of the Hotel Sheraton in San Juan, the capital city, students and supporters clashed with special police forces who arrived to quash the demonstration in the hotel's lobby [EN]. Members of the police riot squad beat demonstrators with batons and used pepper spray against them. At least five students were arrested. Leaders of trade unions, students, and other demonstrators were wounded and transported to nearby clinics and hospitals. Video by Univisión Puerto Rico of violent clashes with demonstrators.

This is yet another incident in the students strike that started April 21, 2010. For almost a month, students have paralyzed the main campus of the state-run University of Puerto Rico (UPR) protesting against $100 million in budget cuts and the proposed elimination of certain registration and fee waivers [EN]. About 20,000 students are enrolled in the main UPR campus in Río Piedras. Ten of the UPR's 11 campuses on the Island -where around 62,000 students study- have joined the protest. The student strike has catalyzed a national social movement that was already displeased with Governor Fortuño's economic and social policies. Artists, politicians, professors, members of trade unions, and activists, from Puerto Rico and the world, have joined the students in solidarity. In the past days, tension has risen in the Río Piedras (main) campus of the UPR. A special police unit has surrounded the campus. Parents have been legally denied the possibility of delivering water, food, and other basic supplies to their kids: students who are participating in the strike. There have been violent police encounters with parents, students, and other people who have supported the strike. In the blog of students maintained by students of Río Piedras, Desde adentro [ES], Mariana Muñiz and Aura Colón offer a detailed account of the incident at the Hotel Sheraton, which forms part of the Convention Center in San Juan: Entonces, los guardias comenzaron a tirar gas pimienta y los manifestantes a huir desesperados hacia el Centro de Convenciones. Varias jóvenes salían llorando y cojeando, mientras gritaban que sus compañeros seguían adentro. En esos momentos, la Policía lanzó una granada de gases lacrimógenos, que cubrieron con una nube blanca gran parte del área y dispersaron aún más a los manifestantes. Toda el área alrededor del hotel estaba rodeada decenas de patrullas. DESDE ADENTRO observó, además, tres ambulancias. Se informó luego que 10 estudiantes se encuentran recibiendo asistencia médica en el Dispensario Hoare, en Miramar. También se notificó que varios estudiantes con dedos rotos y heridas en los brazos fueron atendidos en el Hospital Ashford. On the other hand, blogger Michael Castro believes the Police has to do its job [ES], although he is also against the use of violence: Estoy contra el abuso y apoyo la huelga de los estudiantes en la UPR pero hay que tener varias cosas claras. La Policía de Puerto Rico tiene un trabajo que hacer, siguen órdenes y ahora mismo las órdenes son las de mantener a los huelguistas controlados. Si una manifestación se sale de control no esperen otra cosa que no sea palos y empujones, están haciendo su trabajo. Today, for the first time in Puerto Rican history, professors from the entire UPR system are holding an assembly [ES] in Cayey to discuss the institution's situation. Also, after the UPR temporarily suspended its law suit against various student leaders, negotiations between the Student's Negotiating Committee and the President of the UPR, José Ramón de la Torre, and the President of the Board of Trustees, Ygrí Rivera, started again today [ES]. Online citizen media have been a vital source of information during the student strike. Professor and blogger Mario Nuñez Molina (@digizen) has prepared a list of citizen media in Puerto Rico covering the student strike [ES]. Some of them are: the Río Piedras students blog Desde adentro [ES] and live radio and streaming of students reporting from Río Piedras through Radio Huelga [ES]. UPR es un país [ES] is aggregating the digital citizen and alternative media resources. Huelga Digital [ES] is also republishing and making a compilation of information. Blogger and graduate student Miguel Ríos created another excellent list of resources that includes Facebook, YouTube, and Flickr.
